Struct ParagraphMix 

Source 
pub struct ParagraphMix<P>(/* private fields */);
Expand description

m Text paragraph properties.

The base Text! widget only implements minimal support for paragraphs, rich text widgets will probably segment paragraphs into sub widgets and may ignore PARAGRAPH_BREAK_VAR depending on the source text format.

Implementations§

Source§

impl ParagraphMix<()>

Source

pub fn context_vars_set(set: &mut ContextValueSet)

Insert context variables used by properties in this mixin.

Source§

impl<P: WidgetImpl> ParagraphMix<P>

Source

pub fn paragraph_break(&self, mode: impl IntoVar<ParagraphBreak>)

P Defines paragraphs in the text.

In the base Text! widget this defines how paragraph_spacing and paragraph_indent are applied.

Other rich text widgets usually segment paragraphs into widgets and may ignore this property, depending on the source text format.

Sets the PARAGRAPH_BREAK_VAR.

Source§

impl<P: WidgetImpl> ParagraphMix<P>

Source

pub fn paragraph_spacing(&self, extra: impl IntoVar<ParagraphSpacing>)

P Extra spacing in-between paragraphs.

The default value is 1.em(). Note that paragraph_break defines the entire text as a single paragraph by default, so this will not be applied by default on the base Text! widget.

Sets the PARAGRAPH_SPACING_VAR.

Source§

impl<P: WidgetImpl> ParagraphMix<P>

Source

pub fn paragraph_indent(&self, indent: impl IntoVar<Indentation>)

P Extra spacing added at the start of lines in a paragraph.

This can be set to a width Length to insert spacing at the start of each first line, or it can be set to (Length, true) to hang all lines except the first.

See paragraph_break for how to define paragraphs.

Sets the PARAGRAPH_INDENT_VAR.
